Chrissy Teigen and her oldest children, Luna and Miles, are already getting cozy for Christmas.

Teigen posted a cute family video in partnership with Old Navy on Instagram, Thursday. In the clip, Teigen, 38, snuggled with her two oldest kids, Luna and Miles Stephens, in matching pajamas in front of a Christmas tree.

Luna, 7 1/2, and Miles, 5 1/2, kissed their mom on her cheeks while wearing the same black, buffalo plaid pajama set.

The camera then cut to Teigen wearing the pajama pants underneath a white button-down shirt that she paired with black peep-toe boots, a fuzzy black clutch and a long gray coat. Teigen described the look as a “date night” outfit in her caption.

“Kicking off the holiday season in our Jingle Jammies from @oldnavy!!! Jammies that double as the perfect date night fit when I’m all glammied? Sign me up!” she wrote.

The model and her husband John Legend also share 11-month-old Esti and 6-month-old Wren, who was born in June via a surrogate.

Back in August, Teigen opened up to PEOPLE about transitioning to a family of six — and was candid about her struggle to balance her attention equally among four kids.

“For me, the hardest part is making sure the older ones feel loved and taken care of and just as special as the babies, even though you might have your hands on the babies a lot more,” she said. “There’s a lot of diaper changing and feeding and it seems like you’re coddling these two little babies and they’re not getting enough. I was speaking with my therapist and I was like, ‘I’m having a hard time because I want to make sure that Miles and Luna feel like we still love them.’ “

Still, the Teigen-Legend family has also made time to give back. Before Thanksgiving, Legend and Teigen took Luna and Miles to visit families staying with Ronald McDonald House Charities (RMHC) and cook for them.
